Delegate (similar to C #) in JavaScript

One feature I use extensively in C # is delegate which is a reference type used to reference anonymous or named methods. Especially the classes already implemented in the framework such as Action and Func , as shown below.

public class Program
{
    public static void Main
    {
        ExibirMensagem((s) => 
        {
            Console.WriteLine(s);
        });
    }

    public static void ExibirMensagem(Action<T> actMensagem)
    {
        actMensagem("Exibiu a mensagem");
    }
}

I would need something similar to this, but in JavaScript. I'm new to JavaScript and I do not know how to do this, it may even be something very simple. In Java 6 that does not support this type of behavior, I remember that to get around this and do something similar I used an interface that could be implemented anonymously, as shown below:

public interface IAcao {
    void Executar(String str);
}

public class Program {
    public static void Main(string[] args) {
        ExecutarAcao(new IAcao() {
            @Override
            public void Executar(String str) {
                Log.v("Exec", str);
            }
        });
    }

    public static void ExecutarAcao(IAcao delAcao) {
        delAcao.Executar("Executou Ação");
    }
}

Is this approach possible in JavaScript?
